Daily Mail War activist Cindy Sheehan- who famously picketed former President George Bush’s Texas ranch in protest of her son being killed in the war in Iraq- is now on the brink of a financial battle with the federal government.

Cindy Sheehan practices Civil Disobedience by nonconsent to taxation

The distraught mother has not paid her taxes since her son Casey was killed in 2004 and now the Internal Revenue Service is suing her for her financial records, which is the first step to claiming back taxes.

‘I feel like I gave my son to this country in an illegal and immoral war and I’ll never get him back’ she said.

‘If they can give me my son back then I’ll pay my taxes and that’s not going to happen,’ she told Sacramento News10.

Ms Sheehan has spoken out a number of times in the past about the fact that she has not paid taxes for the past seven years, and she does not plan to succumb to their threats of action.

‘The Feds have thrown down the gauntlet against someone who has absolutely not one ounce of fear of them, and when it’s over, they’ll know they have been in a fight,’ she wrote on her blog.

She also said that the first time she was notified about the lawsuit was when the News10 journalist approached her for the interview.

‘Isn’t it nice of the IRS to tell the media where to ambush me before they tell me that the US Attorney is suing me?’ she wrote.

Ms Sheehan has continued her anti-war campaign since she first gained national attention by creating so-called Camp Casey in front of former President Bush’s Crawford, Texas ranch in 2005.

While still an outspoken activist against both the wars in Iraq and Afghanistan, she has also expanded her issue base and become involved in the Occupy Sacramento movement.

She was arrested in October while she participated in the anti-Wall Street protests.

In regards to the IRS’s tax claim, it is unclear how much the former youth minister is worth, though she did publish two books, titled Dear President Bush and Peace Mom: A Mother’s Journey Through Heartache To Activism.

Still, she seems determined to stand her ground against what she calls the evil ‘empire’ that America has become.

‘I paid my taxes for, you know, what- 30 years before my son was killed?’ she despondently told News10.
